Why am I receiving attempt to index nil with 'Name'?

So I followed a tutorial on how to create a security camera system created by kingerman88, all went well and I had the cameras pulled up and able to start switching cameras. I tried to switch cameras again after the 4th time and an error came up stating "attempt to index nil with 'Name' - Line 26" and nothing happens. I press switch camera again and it works fine until I hit the 4th camera, then the same error.

local remoteEvent = game.ReplicatedStorage:WaitForChild('CameraEvent')
local Player = game.Players.LocalPlayer
local Character = Player.Character or Player.CharacterAdded:Wait()
local Camera = workspace.CurrentCamera
local LeftArrow = script.Parent.LA -- Create extra definitions for easy use
local RightArrow = script.Parent.RA
local CameraName = script.Parent.CameraName

Camera.CameraType = Enum.CameraType.Scriptable 

local Cameras = game.Workspace.Cameras:GetChildren() -- this is the table of all the cameras
local index = 1

function ChangeCamera() -- This function will be fired when a button is pressed
	if index < 1 then -- The index is less than 0 so we will put the last camera in the table
		index = #Cameras + 1
	elseif index > (#Cameras + 1) then -- You reached the last camera
		index = 1
	end

	if index == 0 then -- When the index is 0 set the camera to the player
		CameraName.Text = "Nil"
		Camera.CameraType = Enum.CameraType.Scriptable 
		Camera.CameraSubject = Character.Humanoid
	else
		CameraName.Text = " "..Cameras[index].Name -- This is the camera part's name
		Camera.CameraType = Enum.CameraType.Scriptable 
		Camera.CFrame = Cameras[index].CFrame -- The Camera Part's Cframe
	end

end

LeftArrow.MouseButton1Click:Connect(function() --Event for when the button is pressed
	index -= 1 --Changing the index -1
	ChangeCamera() --Fire the function
end)
RightArrow.MouseButton1Click:Connect(function()
	index += 1 
	ChangeCamera() 
end)

Any solutions on what is happening?

Cameraname is nil; it appears it doesn't exist.
